the populations on Day 14 within the control, 2.0, and 10.0 bulb
treatments differed significantly from one another (P < 0.0001,
F2,36 = 13.93). Fecundity was significantly higher for the control
treatment at 3.18 ± 0.57 eggs individual−1 than the 2.0 bulb
at 1.3
±
0.48 eggs individual−1 (Tukey’s HSD P < 0.05) and the
10.0 bulb treatment at 0.49
±
0.12 eggs individual−1 (Tukey’s HSD
P < 0.0001). Additionally, fecundity in the 2.0 bulb treatment was
significantly higher than the 10.0 bulb treatment (P < 0.01). The
59–64% decrease in fecundity for animals in the 10.0 bulb treatment
occurred despite the fact that we found no difference in mortality
among treatments when animals were free to migrate into shaded
and dark regions, and that eggs were laid in the dark region.
